I have Mac Mini 1.5 solo that work very well for me and my son untill we updated the EFI 1.1 a week ago and never booted back up. I call apple and was told bad hardware maybe caused by update they send me to a Apple store to get it checked but there they said it was the power button not the flash. I had it plug in to the wall the hole time at home but when i took it there it booted as soon as he plug it in so he shut down and it did not boot, he unplug it for a few seconds plug it back no good with button but did boot a few second by itself. I replaced the button my self for a few hunder less then what Apple Was asking for (160.00 less). Still not luck. I feel i got screwed by Apple on this. Has anyone seen this and how it fix....
